Zhang Xiaohua saw Liu Xiao frowning and thinking for about ten minutes, and she couldn't bear it anymore, "Have you thought about it?"

"Don't argue, don't argue!" Liu Xiao was interrupted again as soon as he figured out some ideas, "I'm thinking!"

Zhang Xiaohua couldn't think of anything to do when she saw Liu Xiao for a while, so she stood up, "I'll go back first, and when that Wu Yue Overlord goes online, you must remember to inform me!"

"Okay, okay, I remember!" As soon as Liu Xiao heard this, he quickly jumped up from the chair and sent Zhang Xiaohua out like a plague god.

Liu Xiao is so ink, it's not that he is afraid, if Wu Yue Overlord is really an evil sword, Liu Xiao will be even happier, he has waited for so long, he is waiting for a chance to compete with the evil sword fairly. Although the last time the evil sword stole Liu Xiao's plan and then took it for himself was quite dirty, Liu Xiao hated it to the extreme, but he would not make the same dirty revenge as the evil sword, he always believed that if he wanted to defeat the opponent, he must be like stepping on the snow without a trace, above board, and defeat the other party with real swords and guns, even if it is not good, it should be as bright and upright as Zhang Xiaohua.

Therefore, Liu Xiao is now digging out his mind, trying to come up with a foolproof plan, to slap that Wu Yue overlord, or maybe the evil sword, to death, and not give the other party any chance to fight back.

Looking at the office, there was nothing to do, Liu Xiao simply closed the office door and went directly back to his room. When I turned on the computer, I saw that the Trojan program was still persistently accessing the domain name, but the link had not been established yet, and Wu Yue Bawang didn't know what he was busy with, so he hadn't been online for so long.

Liu Xiao stopped the operation of the Trojan and then opened the decompilation software, he wanted to see the structure and function of the Trojan. Liu Xiao had studied various mainstream Trojans before, if Wu Yue Overlord's Trojan horse was not designed by himself, but modified from common Trojans, then Liu Xiao thought that he should have a way.

After decompiling the Trojan horse, Liu Xiao opened the Trojan database he had studied before, and there are various Trojan feature codes that he had summarized, as long as he looked for those feature codes in the decompiled code, once the same feature code appeared, it could be said that the two Trojans were the same program, or that there was a certain connection between the two.

Liu Xiao compiled a small program, and the program will search one by one according to the feature code in Liu Xiao's Trojan database, and record it if it finds the same.

The results came out quickly, there are only two identical feature codes, Liu Xiao checked the database, these two feature codes are from the same Trojan, from this point of view, the Trojan used by Wu Yue Overlord must have something to do with this Trojan.

After Liu Xiao called up the relevant information of this Trojan horse, he was a little surprised, this is not a mainstream Trojan horse, it was obtained by chance two years ago. At that time, Liu Xiao participated in an anti-virus forum, where there were some folk anti-virus enthusiasts, and their greatest interest was to collect all kinds of viruses and Trojans, and then after some analysis, give solutions and removal plans.

Although a long time has passed, Liu Xiao still has a certain impression of this Trojan horse, he remembers that someone on the forum at that time released this Trojan program, saying that it had just been caught, but he couldn't take off the shell of the Trojan horse, and hoped that the master would study it. Liu Xiao downloaded the Trojan horse program, and then it took more than a month to find the entrance to the program, and successfully unshelled, and then after some analysis, he found a way to completely remove the Trojan horse.

But when Liu Xiao was about to publish his analysis results on the forum, he found that everyone had forgotten about this Trojan horse, and Liu Xiao was not famous at that time, and he belonged to the rookie level, so he was embarrassed to publish it again.

Liu Xiao looked at the two feature codes, one of which was converted, is the letter "wufeifan", this string of letters is very likely to be the name of the author of the Trojan horse, Liu Xiao also deliberately checked it back then, among the people in the circle he knew, no one called this name, so Liu Xiao was still very puzzled back then, because according to Wufeifan's technology of shelling the Trojan, this person must be a top master, and he will never be nameless.

Another feature code is a piece of code in the Trojan daemon, because it is very technically representative, Liu Xiao also set it as one of the characteristics of this Trojan.

Through these two feature codes, a basic judgment can already be drawn that the Trojan horse used by Wu Yue Overlord should be designed by Wufeifan. Liu Xiao couldn't help sighing, two years ago, this wufeifan's technology was already quite good, I didn't think that after two years, his technology has not improved at all, which can be known from the code of the daemon, he still uses the guardian method two years ago.

"It seems that once a person gets into the eye of money, he will no longer have technology in his heart!"

Liu Xiao sighed, a little sorry for this wufeifan, if this guy puts all his mind into technology, then he will definitely not be inferior to the five masters now, but unfortunately, this guy puts all his energy on writing Trojan horses and collecting protection money.

When Wufeifan designed the Trojan two years ago, he set up a super backdoor, which is also a common problem of ordinary programmers, and he always has to save a hand for himself. If someone accidentally falls into the Trojan horse, as long as you press a combination of keys designed by Wufeifan, the backdoor will be activated, and then enter the super password, the control end of the Trojan and the controlled end will be inverted instantly, and the dismounter will not only not be able to control the broiler, but will be firmly monitored by the owner of the broiler.

This kind of programming habit of keeping one hand is deep-rooted, and Liu Xiao can know without guessing that there must be a super backdoor in the Trojan horse that Wu Yue Overlord is using now.

"Then this Wu Yue Overlord may not be the Evil Sword, at least not the Evil Sword himself. Liu Xiao scratched his head, a master like the evil sword is good at infiltrating and breaking in an instant, and basically he will not use a Trojan horse, and even if he does, he will never use a Trojan horse designed by others.

Liu Xiao stopped his thoughts for the time being, he had to hurry up and find the super password set by Wufeifan in these decompiled codes, as well as the method to activate the backdoor. Fortunately, Liu Xiao has done this kind of work many times, and it is not the first time he has come into contact with Wufeifan's writing habits, and it took about ten minutes for him to find the location of the super password.

Convert it over, it is an encrypted character, Liu Xiao looked at it, he knew that this was a very common encryption algorithm, and it was also very common, Liu Xiao he found the *** of this encryption algorithm, and entered this character, and he got the super password, "10000000".

Liu Xiao couldn't help but sweat wildly, this wufeifan is really crazy, you can see his thoughts from the password, he wants to make 100 million, otherwise he will never set such a mentally retarded password.

Knowing that Wu Yue's overlord was not an evil sword, Liu Xiao was a little disappointed, the imaginary fierce duel would definitely not be there, and there was no motivation for revenge, Liu Xiao's fighting spirit suddenly lost more than half. The current Wu Yue overlord is like a fish on the chopping board, and he, a guy who dismounts others everywhere, is destined to die on his own horse in the end.

LIU XIAO PUT THE TROJAN HORSE INTO HIS VIRTUAL SYSTEM AND RAN IT AGAIN, AND THEN SENT A MESSAGE TO WU YUE'S EMAILS, "ARE YOU FREE?" ”

In about ten minutes, Wu Yue Overlord was launched, and Liu Xiao saw that his Trojan had successfully established a link with the other party.

Wu Yue's message came, "Why didn't you reply to the message yesterday? How long are you going to pay the protection fee?", probably Wu Yue thought that Liu Xiao took the initiative to come to him, so he must have agreed to pay the protection fee.

"Let's not talk about the protection fee, I have a question for you, you are so unscrupulous to collect protection money, you don't think about what to do if someone catches the handle if you miss?" Liu Xiao replied.

"Hahaha, handle? I might as well tell you the truth, everything in the network is virtual data, you can't see it or touch it, and it's harder to grab a real handle than to climb to the sky. For now, you know I'm intimidating you, but what can you do? You don't even know who I am, I can find you anytime and anywhere, but it's not so easy for you to find me. Wu Yue Overlord seemed to be very proud, "You don't have other thoughts as soon as possible, so as not to steal chickens and rice when you get it." This sentence can be regarded as a threat, probably Wu Yue Overlord also heard that Liu Xiao's question was unfriendly.

"Are you really going to do this to the end?" Liu Xiao continued to ink.

"Are you Tang Seng or not Tang Seng?" Wu Yue Overlord finally became angry, "Since you called me online, you have to give me an answer today, miss this time, even if you kneel on the ground and beg for mercy next time, we will never let you Zhang go." ”

Liu Xiao sighed, no longer replied, and then switched to his own virtual system, activated the back door of the Trojan, just a moment, Liu Xiao entered the other party's machine through the Trojan, he first copied the other party's log records, including the use of the Trojan horse, to his own machine, and then looked for useful things in the other party's machine.

When he saw the display of the control end of the opponent's Trojan, Liu Xiao couldn't help but be taken aback, there were thousands of broilers in the hands of this Wu Yue overlord, and there were more than 400 Trojans on the line at this time. Liu Xiao flipped through the other party's computer, and finally found a file, which was a report made by Wu Yue Bawang, which contained detailed accounts of the protection fees paid by various companies, including how much to pay, how many months it had been paid, and the account accounts for remittances, and there were more than 100 large and small accounts in various banks. At the end of the file, another table is attached, on which are the enterprises that need to be reminded and have not yet paid the protection fee, and the Zhang and Liao families are all on it.

"Damn! it's really fucking professional enough!", Liu Xiao scolded secretly, and copied all the things that could be searched on the other party's machine, including the username of the other party's machine, the account and password used for dialing, he copied them all, with this information, it should not be difficult to know the physical location of the other party.

Poor Wu Yue Overlord didn't know that he had been controlled, so he waited there stupidly, seeing that Liu Xiao didn't reply for a long time, he sent Liu Xiao an ultimatum, "What do you mean? If you don't reply, you won't have a chance again!" And his action happened to be monitored by Liu Xiao throughout the whole process, and these data were saved by Liu Xiao as evidence.

Liu Xiao smiled and replied, "I won't give you a chance anymore, just let the horse come!"

Wu Yue was furious, "Okay, you kid wait, there will be your Zhang's good fruits to eat in the future!"

Liu Xiao didn't bother to pay attention to him, he had already found all the information he should be looking for, and the rest of the matter of finding out and catching Wu Yue's overlord was not something he could solve. Liu Xiao sorted out all the data he had just gotten, and deliberately made a backup to the USB flash drive, turned off the computer with his hand, sat in the chair and sighed: "Heaven is evil, you can still live, you can do your own evil, you can't live." I've given you all the opportunities that should be given, and if you want to blame it, you don't want to grasp it, and now, I have no choice but to let the little flower bite you. ”

As soon as these words came out, a layer of cold sweat broke out on Liu Xiao's head, and he actually forgot Zhang Xiaohua's instructions, Liu Xiao hurriedly took out his mobile phone and notified Zhang Xiaohua, "Hey, Xiaohua, that Wu Yue overlord is online!"

"Okay, good!" Zhang Xiaohua was overjoyed, "I'll be there soon!"

Liu Xiao got up to wipe the cold sweat, put the USB flash drive in his pocket, and then looked at his arm, it seemed that the place that was twisted by Zhang Xiaohua in the morning began to turn purple again, Liu Xiao felt his scalp tighten for a while, "Good girl, this is dead!"

Virtual Systems:

Many people have had the experience of installing multiple operating systems, but unfortunately, no matter how many systems are installed, only one of them can be started at startup.

VIRTUAL SYSTEM TECHNOLOGY CAN INSTALL MULTIPLE OPERATING SYSTEMS ON ONE MACHINE, THESE OPERATING SYSTEMS CAN BE STARTED AT THE SAME TIME, AND CAN BE SWITCHED AT WILL, AND THEY CAN COMMUNICATE WITH EACH OTHER, AND EVEN YOU CAN BOOT WINDOWS AND LINUX SYSTEMS ON ONE MACHINE AT THE SAME TIME. This technology is mainly to facilitate platform switching and can prevent viruses.
